Urodynamics is a test we do in our office to help us understand how the bladder functions - how the bladder stores urine, how the bladder empties urine and how the sphincter and the muscles of the bladder act. It helps us determine the problem with the bladder. The test is simple; it takes about ten minutes and is performed in the doctor's office. We ask patients to arrive with a full bladder. We then have them urinate into a container. The volume of urine is measured at the rate at which the bladder empties. We then insert a thin catheter or a tube into the bladder, and another thin catheter into the vagina. We continue to pump water into the bladder. More measurements are taken from the first urge to urinate until you can't hold it anymore.
Who's a candidate for Urodynamics?
A good candidate for this test is a patient who has urinary difficulty - incontinence, frequent urination, sudden -- strong urges to urinate, problems starting to urinate, painful urination, problems completely emptying the bladder and frequent urinary tract infections.
What are the benefits of Urodynamics?
If the tests show - stress urinary incontinence, the treatment is a minor procedure to tone the sphincter. If the tests show - urge-type incontinence, the treatment is a pill to relax the bladder muscle. If the tests show - a small bladder capacity or a big capacity, the treatment is behavior modification.
What are the risks of Urodynamics?
There is some minor discomfort with this test when the catheter is inserted.
